PIVOT-MOUNT FOR GUNS.

Specification of Letters Patent.

Application filed March 23, 1914. Serial No. 826,689.

To all "whom-it may 0011 ("era Be it known that I, Nonnnnr Kocinresiding at Essen-Rellinghausen, Germany, a,

subject of the Emperor of (irermany, have lnvented a certain new and useful Improvement in Pivot-Mounts for Guns, of which "the following is a specification.

The subject matter of the present invention resides in a pivot mount for guns intended for field use.

In the accompanying drawing one embodiment-of the invention is illustrated, and

Figure-1 shows a side view, in firing position, of the gun mount with one wheel removed; Fig. 2 a corresponding front view partly in section; Fig. 3 a top plan view of Fig; 1; Fig. 4, a side view of. the gun mount with the parts in the position which they will take during the transformation from firing to traveling position; and Fig.

5 a side view of the gun mount and limher in limbered-up position.

The gun mount comprises a pivot mounting, the pedestal of which consists of two portions A and B. The lowerportion A of the pedestal which is provided with a liinher eye 0 The upper portion B of the pedestal carries a vertical trunnion D, around which the trun-.

nion fork E may be trained by..means of a training gear, not shown in the drawing, and which is inserted between the trunnion fork and the pedestal portion B. The trunnion fork has hearings for the horizontal trunnions f of the guide carrier F, onthe under side of which the gun barrel G is guided. Between the trunnion fork and the guide carrier is inserted an elevating gear not shown in the drawing. ()n the trunnion fork are provided axle armsJ for carriage wheels K, and two eyelets e the use of which will be fully explained tarther on.

I On the forward side of the pedestal portion B is provided an eyelet 7) which engages hetween two other eyelets (1. arranged on the pedestal portion A and which may he secured therein by means of a key holt ll, see Figs. 1, 2 and 3. A claw (1/ is moreover provided at the rear side of the pedestal portion A, which is intended to engage with a corresponding elawor recess in the ped- Lastly two pair of links atedon the foundation plate 0: These-links the pedestal portion B and the pedestal portion A. The eyelet b is crmpled'with t on a f u d tio pl te C Y together with the wheels K, the guide ear;

M N are journaled on. the pedestal 'p'o B loy means of studs b and respective which extend from lateral projectio ns o f the pedestal portion B. The links M lia-ve hinged connections with the studs a fi ot the pedestal portion A whilethe links N engage. with studs 41 in bearingse ii 'hichares'tri 60 are so constructed that they, together with portion A and the-foundation. plate'G ter link parallelograms. The. forward 15*. i the foundation plate 0 is narrowerdihan the rear portion so that the wheels "K may rest on the ground'with the mount iiiemhers inthe position represented in Fi YVith the gun in tiring position. see; 1, 2 and 3, the foundation plate C re 's" the ground and the portion B on the pedestal the eyelets a by means of the .key bolt and the claw d eng-ages with the correspond 7' ing claw otthe pedestal portion B;""'the wheels are raised from the ground. In this position of the parts, the trunnion'iork ll rier F and the gun barrel (i may he' tiained 8 360 relative to the pivot ped estal' 'A" B, .and the gun tired in each direction at i igh est possihle elevation .with sutlici enflstability. i To prepare the gun mount "for traveling, s the key holt ll is first removed from the eyelets a I) and the pedestal portion 13 together with the links M N, the trunnion fork l), the wheels K, etc., is swung forward until the wheels K strike the. ground, see Fig. 4. 9 in order to provide room for the eyelets a rats 11",.l ig. l, have been made in the pedes- The foundation plate (7 together with the pedestal. A and the links M N is thereupon raised until 9 the foundation plate abuts against the eyelet I), see Fig. 5. Lastly the eyelctsrz are secured in the eyelets (2 by means of a bolt ll and the carriage is lin'lhrrrd up hy bringing the trail eye in engagement with the hook p of a limher l. A t'ter unlinihering the'inount, the bolt H is first removed from the eyelets Ida, thereupon the foundation plate (1; together with the pedestal portion A is laid down on th -"round and the pedcsh tal portion B lastly swung rearward, up on tion plate and said pedestal, whereby the.

mount may be transferred from traveling to firing posltion.

2. A pivot mount for guns comprising a fork with trunnion bearings, axle arms for the carriage wheels on said fork, a pedestal on which said fork is mounted to turn around a vertical axis, said pedestal having an upper portion and a lower portion, a foundation plate on which said lower portion of the pedestal is rigidly secured; link connection between said foundation plate and said upper portion of the pedestal, whereby the upper portion may be displaced from engagement with the lower portion and moved toward the foundation plate.

3. A pivot mount for guns comprising a fork with trunnion bearings, axle arms for the carriage wheels on said fork, a pedestal on which said fork is mounted to turn around a vertical axis, said pedestal having an upper portion and a lower portion, a foundation plate on which said lower pordtion of the pedestal is rigidly secured; link connection between said foundation plate and said upper portion of the pedestal,

whereby the upper portion may be displaced from engagement with the lower portion and moved toward the foundation plate; suitable members for securing the upper portion of the pedestal in the two po sitions.

4. A pivot mount for guns comprising a fork with trunnion bearings, axle arms for the carriage wheels on said fork, a pedestal on which said fork is mounted to turn around a vertical axis, said pedestal having an upper portion and a lower portion, a foundation plate on which said lower portion of the pedestal is rigidly secured; link connection between said foundation plate and said upper portion of the pedestal, wherebyjhe upper portion may be displaced from engagement with the lower portion and moved toward the foundation plate,

said foundation plate having one portion narrower than the track of the wheels.

5. A pivot mount for guns comprising a fork with trunnion bearings, axle arms forthe carriage wheels on said fork, a pedestal on which said fork is mounted toturn around a vertical axis,said pedestal havingan upper portion and a lower portion, a foundation plate on which said lower portion of the pedestal is rigidly secured; link connection between said foundation plate and said upper portion of the pedestal, whereby the upper portion may be displaced from engagement with the lower portion and moved toward the foundation plate; said foundation plate being provided with a limber eye.
